LAPS - Laser Aided F.owder S.olidification - Technology for the direct production of metallic and polymer parts
MetadataShow full item record
The prototypes of today's commercial available RP-Systems (e.g. StereolithographySystems) are suitable mainly for designing and, if even, for restricted functional tests. From this it can be concluded that for obtaining functional or technical prototypes one has to use time- and cost-intensive downstream-technologies like investment casting. Because of the economical aspects in industries there is a great demand for direct production of functional and technical prototypes. The present paper describes the activities and research results on the development techniques based on laser induced solidification of powder materials for the direct manufacturing ofmetallic parts. Also a various number of polymers, suitable for sintering and remelting, are investigated and presented as functional materials for different applications.
